Our analysis of the samples reveals evidence suggesting that Hacking Team’s developers themselves are actively continuing the development of this spyware. ## From Hacking Team to Hacked Team to…? Since being founded in 2003, the Italian spyware vendor Hacking Team gained notoriety for selling surveillance tools to governments and their agencies across the world. |Col1|Col2|Search| |---|---|---| |Type your keyword...

Following the hack, the security community has been keeping a close eye on the company’s efforts to get back on its feet. The first reports suggesting Hacking Team’s resumed operations came six months later – a **[new sample of Hacking Team’s Mac spyware was apparently in the](https://reverse.put.as/2016/02/29/the-italian-morons-are-back-what-are-they-up-to-this-time/)** wild.

Our further research uncovered several more samples of Hacking Team’s spyware created after the 2015 hack, all being slightly modified compared to variants released before the source code leak. The samples were compiled between September 2015 and October 2017. We have deemed these compilation dates to be authentic, based on ESET telemetry data indicating the appearance of the samples in the wild within a few days of those dates. Further analysis led us to conclude that all the samples can be traced back to a single group, rather than being isolated instances of diverse actors building their own versions from the leaked Hacking Team source code. One indicator supporting this is the sequence of digital certificates used to sign the samples – we found six different certificates issued in succession. Four of the certificates were issued by Thawte to four different companies, and two are personal certificates issued to Valeriano Bedeschi (Hacking Team co-founder) and someone named Raffaele Carnacina, as shown in the following table: ----- |Valeriano Bedeschi|8/13/2015 – 8/16/2016| |---|---| |Raffaele Carnacina|9/11/2015 – 9/15/2016| |Megabit, OOO|6/8/2016 - 6/9/2017| |ADD Audit|6/20/2016 - 6/21/2017| |Media Lid|8/29/2016 - 8/30/2017| |Ziber Ltd|7/9/2017 - 7/10/2018| The samples also have forged Manifest metadata – used to masquerade as a legitimate application – in common, appearing as “Advanced SystemCare 9 (9.3.0.1121)”, “Toolwiz Care 3.1.0.0” and “SlimDrivers (2.3.1.10)”. Our analysis further shows that the author(s) of the samples have been using VMProtect, apparently in an effort to make their samples less prone to detection. This was also common among pre-leak Hacking Team spyware. The connections among these samples alone could have originated with virtually any group repurposing the leaked Hacking Team source code or installer – as was the case with **Callisto** **Group in early 2016. We have, however, collected further evidence that ties these post-leak** samples to Hacking Team’s developers themselves. The versioning (which we accessed after overcoming VMProtect protection) observed in the analyzed samples continues where Hacking Team left off before the breach, and follows the same patterns. Hacking Team’s habit of compiling their payloads – named Scout and Soldier – consecutively, and often on the same day, can also be seen across the newer samples. The following table shows the compilation dates, versioning and certificate authorities of Hacking Team Windows spyware samples seen between 2014 and 2017. Reuse of leaked source code by Callisto Group is marked in red. **Compilation date Scout version Soldier version Certificate issued to** 2014-11-27 1007 Open Source Developer, Muhammad Lee's 2014-12-05 11 Open Source Developer, Muhammad Lee's 2014-12-12 12 1008 **[Open Source Developer, meicun ge](https://citizenlab.ca/2015/03/hacking-team-reloaded-us-based-ethiopian-journalists-targeted-spyware/)** 2015-03-19 1009 Open Source Developer, meicun ge 2015-03-27 13 Open Source Developer, meicun ge **JULY 2015 LEAK** 2015-09-04 15 Valeriano Bedeschi 2015-10-19 16 1011 Raffaele Carnacina 2016-01-05 13 SPC 2016-01-18 17 Raffaele Carnacina 2016-03-24 18 1012 Raffaele Carnacina 2016-06-17 1014 Megabit, OOO 2016-08-02 21 1016 Megabit, OOO |Compilation date|Scout version|Soldier version|Certificate issued to| |---|---|---|---| |2014-11-27||1007|Open Source Developer, Muhammad Lee's| |2014-12-05|11||Open Source Developer, Muhammad Lee's| |2014-12-12|12|1008|Open Source Developer, meicun ge| |2015-03-19||1009|Open Source Developer, meicun ge| |2015-03-27|13||Open Source Developer, meicun ge| |JULY 2015 LEAK|||| |2015-09-04|15||Valeriano Bedeschi| |2015-10-19|16|1011|Raffaele Carnacina| |2016-01-05|13||SPC| |2016-01-18|17||Raffaele Carnacina| |2016-03-24|18|1012|Raffaele Carnacina| |2016-06-17||1014|Megabit, OOO| ----- |2016-12-19|23|1018|ADD Audit| |---|---|---|---| |2017-01-31|24|1019|ADD Audit| |2017-04-28|25|1020|ADD Audit, Media Lid| |2017-06-28|27|1022|Media Lid, Ziber Ltd| |2017-10-09|28||Ziber Ltd| |2017-10-18||1025|Ziber Ltd| Furthermore, our research has confirmed that the changes introduced in the post-leak updates were made in line with Hacking Team’s own coding style and are often found in places indicating a deep familiarity with the code. It is highly improbable that some other actor – that is, other than the original Hacking Team developer(s) – would make changes in exactly these places when creating new versions from the leaked Hacking Team source code. One of the subtle differences we spotted between the pre-leak and the post-leak samples is the difference in Startup file size. Before the leak, the copied file was padded to occupy 4MB. In the post-leak samples, this file copy operation is padded to 6MB – most likely as a primitive detection evasion technique. ----- Figure 1 – Startup file size copy changed from 4 MB pre-leak to 6MB post-leak We found further differences that fully convinced us of Hacking Team’s involvement. However, the disclosure of these details could interfere with the future tracking of the group which is why ----- The functionality of the spyware largely overlaps with that in the leaked source code. Our analysis so far has not confirmed the release of any significant update, as **[promised by Hacking](http://www.hackingteam.it/news/2015/07/13/statement-from-CEO.html)** Team following the hack. As for the distribution vector of the post-leak samples we analyzed, at least in two cases, we detected the spyware in an executable file disguised as a PDF document (using multiple file extensions) attached to a spearphishing email. The names of the attached files contain strings likely aimed to reduce suspicion when received by diplomats. ----- Figure 2 – Investigation timeline ## Conclusion Our research lets us claim with high confidence that, with one obvious exception, the post-leak samples we’ve analyzed are indeed the work of Hacking Team developers, and not the result of source code reuse by unrelated actors, such as in the case of Callisto Group in 2016. As of this writing, our systems have detected these new Hacking Team spyware samples in fourteen countries. We choose not to name the countries to prevent potentially incorrect attributions based on these detections, since the geo-location of the detections doesn’t necessarily reveal anything about the origin of the attack. ## IoCs **ESET detection names** Trojan.Win32/CrisisHT.F Trojan.Win32/CrisisHT.H Trojan.Win32/CrisisHT.E Trojan.Win32/CrisisHT.L Trojan.Win32/CrisisHT.J Trojan.Win32/Agent.ZMW Trojan.Win32/Agent.ZMX Trojan.Win32/Agent.ZMY Trojan.Win32/Agent.ZMZ **Samples signed by Ziber Ltd** Thumbprint: 14 56 d8 a0 0d 8b e9 63 e2 22 4d 84 5b 12 e5 08 4e a0 b7 07 Serial Number: 5e 15 20 5f 18 04 42 cc 6c 3c 0f 03 e1 a3 3d 9f ----- 2eebf9d864bef5e08e2e8abd93561322de2ab33b 51506ed3392b9e59243312b0f798c898804913db 61eda4847845f49689ae582391cd1e6a216a8fa3 68ffd64b7534843ac2c66ed68f8b82a6ec81b3e8 6fd86649c6ca3d2a0653fd0da724bada9b6a6540 92439f659f14dac5b353b1684a4a4b848ecc70ef a10ca5d8832bc2085592782bd140eb03cb31173a a1c41f3dad59c9a1a126324a4612628fa174c45a b7229303d71b500157fa668cece7411628d196e2 eede2e3fa512a0b1ac8230156256fc7d4386eb24 **C&Cs** 149.154.153.223 192.243.101.125 180.235.133.23 192.243.101.124 95.110.167.74 149.154.153.223 **Samples signed by ADD Audit** Thumbprint: 3e 19 ad 16 4d c1 03 37 53 26 36 c3 7c a4 c5 97 64 6f bc c8 Serial Number: 4c 8e 3b 16 13 f7 35 42 f7 10 6f 27 20 94 eb 23 **SHA-1 samples** 341dbcb6d17a3bc7fa813367414b023309eb69c4 86fad7c362a45097823220b77dcc30fb5671d6d4 9dfc7e78892a9f18d2d15adbfa52cda379ddd963 e8f6b7d10b90ad64f976c3bfb4c822cb1a3c34b2 **C&Cs** 188.166.244.225 45.33.108.172 178.79.186.40 95.110.167.74 173.236.149.166 **Samples signed by Media Lid** Thumbprint: 17 f3 b5 e1 aa 0b 95 21 a8 94 9b 1c 69 a2 25 32 f2 b2 e1 f5 Serial Number: 2c e2 bd 0a d3 cf de 9e a7 3e ec 7c a3 04 00 da **SHA-1 samples** ----- 27f4287e1a5348714a308e9175fb9486d95815a2 71a68c6140d066ca016efa9087d71f141e9e2806 dc817f86c1282382a1c21f64700b79fcd064ae5c **SHA-1 samples** 27f4287e1a5348714a308e9175fb9486d95815a2 71a68c6140d066ca016efa9087d71f141e9e2806 dc817f86c1282382a1c21f64700b79fcd064ae5c **C&Cs** 188.226.170.222 173.236.149.166 **Samples signed by Megabit, OOO** Thumbprint: 6d e3 a1 9d 00 1f 02 24 c1 c3 8b de fa 74 6f f2 3a aa 43 75 Serial Number: 0f bc 30 db 12 7a 53 6c 34 d7 a0 fa 81 b4 81 93 **SHA-1 samples** 508f935344d95ffe9e7aedff726264a9b500b854 7cc213a26f8df47ddd252365fadbb9cca611be20 98a98bbb488b6a6737b12344b7db1acf0b92932a cd29b37272f8222e19089205975ac7798aac7487 d21fe0171f662268ca87d4e142aedfbe6026680b 5BF1742D540F08A187B571C3BF2AEB64F141C4AB 854600B2E42BD45ACEA9A9114747864BE002BF0B **C&Cs** 95.110.167.74 188.226.170.222 173.236.149.166 46.165.236.62 **Samples signed by Raffaele Carnacina** Thumbprint: 8a 85 4f 99 2a 5f 20 53 07 f8 2d 45 93 89 af da 86 de 6c 41 Serial Number: 08 44 8b d6 ee 91 05 ae 31 22 8e a5 fe 49 6f 63 **SHA-1 samples** 4ac42c9a479b34302e1199762459b5e775eec037 2059e2a90744611c7764c3b1c7dcf673bb36f7ab b5fb3147b43b5fe66da4c50463037c638e99fb41 9cd2ff4157e4028c58cef9372d3bb99b8f2077ec ----- cc209f9456f0a2c5a17e2823bdb1654789fcadc8 99c978219fe49e55441e11db0d1df4bda932e021 e85c2eab4c9eea8d0c99e58199f313ca4e1d1735 141d126d41f1a779dca69dd09640aa125afed15a **C&Cs** 199.175.54.209 199.175.54.228 95.110.167.74 **Samples signed by Valeriano Bedeschi** Thumbprint: 44 a0 f7 f5 39 fc 0c 8b f6 7b cd b7 db 44 e4 f1 4c 68 80 d0 Serial Number: 02 f1 75 66 ef 56 8d c0 6c 9a 37 9e a2 f4 fa ea **SHA-1 samples** baa53ddba627f2c38b26298d348ca2e1a31be52e 5690a51384661602cd796e53229872ff87ab8aa4 aa2a408fcaa5c86d2972150fc8dd3ad3422f807a 83503513a76f82c8718fad763f63fcd349b8b7fc -----
